Thanks to both of you very much for the suggestions.
Unfortunatelly I feel too weak to answer all of them, but will definately consider them.
In brief, I started the molybdenium today and will try to have meat again in few days. If I'm blessed enough to be able to have fish ever again in my life will do my best to try salmon instead of meat. Now I can't due to mercury, last time it gave me not only brain fog but also severe depression.
My country is in very bad state. We don't have many common tests in the USA, I'm refering to the ELISA one. But I believe your theory for stomach infections is true and I hope to address is with my EAV practitioner ASAP.
I know glutamine will not cure leaky gut, it helps put down gut inflammation tough. I think Restore is able to heal the leaky gut. My problem is that I'm yet struggling to up my doses. Full dose is 15 ml per day, last time I could take 1.5 ml or so.
